Abstract. Detailed velocity structure and Moho mapping is of crucial importance for a high precision relocation of seismicity occurring out of, or marginal to, the geometry of seismological networks. Usually the seismographic networks do not cover the boundaries of converging plates such as the Hellenic arc. The crustal thinning from the plate boundary towards the back-arc area creates significant errors in accurately locating the earthquake, especially when distant seismic phases are included in the analysis. The case of the Cephalonia (Ionian Sea, Greece) sequence of JanuaryFebruary 2014 provided an excellent example where the hypocentral precision was greatly affected by the crustal thinning from the plate boundary at the Ionian sea towards the Aegean sea. This effect was examined in detail by testing various velocity models of the region in order to determine an optimal model. Our tests resulted in the adoption of a velocity model that resembles the crustal thinning of the region. Then, a relocation procedure was performed in the Cephalonia sequence for the time period of 26 January to 15 May 2014 by applying probabilistic non-linear location algorithms. The high-precision relocation resulted in an improved spatial distribution of the seismicity with respect to the preliminary locations and provided a reliable basis to examine seismotectonic implications of the Cephalonia sequence.

“…In western Greece there are six stations that operate since early 2006 -mid 2007 (VLSM, RLSO, PONT, SPAN, KASI, KIPO; see www.gein.noa.gr/gps.html for network map and site logs). Ganas et al (2013) presented results showing N-S crustal shortening onshore Lefkada Island of the order of 2-3 mm/yr, which the authors evaluated as "is probably related to increased locking on the offshore Lefkada fault" implying pre-seismic deformation. This paper presents results from data provided by two (2) permanent GPS stations onshore Lefkada (SPAN and PONT) and one station in Cephalonia (VLSM).…”
